从意大利蜜蜂（Apis mellifera）中分离并测序了一个编码主要皇家果冻蛋白（MRJPs）基因家族新成员的cDNA。皇家浆（RJ）是一种分泌物的头腺的护士蜜蜂。RJ的蛋白质组分（12.5%，w/w）的来源和生物学功能尚不清楚。我们发现，MRJP基因家族编码一组密切相关的蛋白质，这些蛋白质与果蝇的黄色蛋白具有共同的进化起源，黄色蛋白在果蝇角质层色素沉着中起作用。MRJPs似乎在蜜蜂中进化出了一种新的营养功能。
A cDNA encoding a new member of the gene family of major royal jelly proteins (MRJPs) from the honeybee, Apis mellifera, was isolated and sequenced. Royal jelly (RJ) is a secretion of the cephalic glands of nurse bees. The origin and biological function of the protein component (12.5%, w/w) of RJ is unknown. We show that the MRJP gene family encodes a group of closely related proteins that share a common evolutionary origin with the yellow protein of Drosophila melanogaster, Yellow protein functions in cuticle pigmentation in D, melanogaster. The MRJPs appear to have evolved a novel nutritional function in the honeybee.
